26-2-302. Witness required to answer questions. A witness shall answer questions legal and pertinent to the matter in issue though the answer may establish a claim against the witness. However, the witness is not required to give an answer that will have a tendency to subject the witness to punishment for a felony or to give an answer that will have a direct tendency to degrade the witness’s character unless the answer is to the very fact in issue or to a fact from which the fact in issue would be presumed.
